After smog pump reinstallment, car wont crank

If car cranked but white smoke came out of the tailpipe.The car may have either a bad head gasket or a cracked cylinder head.You mentioned changeing the radiator.Did the car overheat severely?This would stress the headgasket.The car may not start now because the plugs are wet(water)or the rings have lost their ability to seal compression due to overheating.

I need to replace the smog pump on my 1991 dodge dakota. I looked at the all of the pulleys etc. and can not find which component that I need to loosen and pivot in order to loosen the belt so I can...

If you have the 3.9 V-6, when looking at the engine as you stand in front of your truck. The smog pump is on your right. You will see one bolt running from the front to the rear of the smog pump on the left side. The bolt is about where nine o'clock would be on it if it were a clock. The bolt is a through bolt, and acts as the pivot. It must be loosened and completly removed.
On the right side, at the three o'clock position you will find the adjustment bolt. It comes from the rear of the smog pump to the front bracket. You will see that it does not have a regular looking nut. But, insteed what I call a trapped nut. A design that stops turning when tighten, or loosened by coming into contact with a part, or bracket. After you remove all of the related hoses, etc. the bolts can be removed allowing the smog pump to be removed. Installation is done in the opposite order. The v-belt is also tensioned by "swinging" the smog pump upward.

How do I change the ignition switch in my C1500 1986 GMC 6.2L DIESEL truck? And I put my hand over the muffler and it gets spotted with oil. Is that from the smog pump being disconnected?

you will need a special tool to compress the steering colum lock ring to remove the lock ring clip to the ring and to install it afterwards. Let me know if you have this and i will help you further.

Squealing Smog Control Belt in Humid Climate

I will list some of my experiences with similar problems.

V-belt quality and grade vary a lot and I do mean a lot. Belts can take a set from sitting--anybody with a table saw will attest to this. I would try a new belt first after finding a good parts man. A good alternator shop (rare today) can help here. The smog pump belt is an easy one to change. Try the cheap stuff first.

Smog pumps in my experience do not need a lot of power, especially at idle, but I have had bearing and pump failure on several wipe out a belt. Pull the belt and spin the smog pump by hand.

Belts can glaze and it is not necessarily noticeable. Stamped-steel pulleys polish smooth and won't transmit the power needed. Pulleys can also wear in some strange shapes so a new belt does not fit properly. See if an alternator shop has a cast iron pulley for the alternator. Cast iron does not polish smooth and also wears off any glaze from the belt surfaces. The crank pulleys are stamped-steel but are larger in diameter with a longer wrap angle so slippage is not a problem there.

In my poor days I tried sanding the belts and pulleys to remove the glaze. Too much work and it was only temporary.

I have used a cast iron pulley on a 110 amp alternator with a winch load. A stamped-steel pulley would just smoke the belt when under load (winch drew 225 amps total!). My truck is 70 amp and that is the biggest alternator Ford has with a V-belt that I know of.

I considered removing my smog pump and associated hardware. My experience has been to leave everything intact unless I can replace everything with an earlier, non-smog engine. Doing everything piecemeal has just caused other problems.

Hope this helps.
